🟡scan_site(url, consent)
Runs SniffPup's free passive scan of a live website (takes up to about a minute) and returns the score and the issues found. Every critical issue comes with masked evidence, fix steps and a fix prompt (with no critical issue, one other issue does). Only scan a site the user owns or has permission to test, and set consent to true only after the user confirms: I own this site or have permission to test it, and I agree to the Terms (including individual arbitration), Acceptable Use Policy and Privacy Policy. Free scans are passive: we only look at what any visitor's browser can see.
